I ride on what people THINK is a shared pathway, so I come across a bunch of pedestrians each day. They just don't understand what the painted bike is doing on the asphalt. Ah well, their problem, not mine.
I pass cyclists on the left and check whether I'm clear before I move back to the right. School kids don't understand the road rules yet, I pass them on the right because they try to ride at the center of the pathway. It scares the hell out of them...
I give pedestrians a bit more space than a cyclist. Why? Beats me...
